Back-UPS ES 700 intermittent constant tone

This was originally posted on APC forums on 7/2/2015


Hi there

My APC Back-UPS ES 700 intermittently emits a long constant tone - approx 10 sec.

Power light flashes red then reverts to solid green when tone stops.

Happens randomly several times a day, whether computer is on or off.

Never done this before. Had it for two or three years.

Is battery on way out? Never replaced.

No sign of power loss/fluctuation. Have another UPS elsewhere in house.

Welcome any advice. 

thanks in advance
